A jet airplane is in level flight. The mass of the airplane is m = 8870 kg. The plane travels at a constant speed around a circular path of radius R = 9.33 miles and makes one revolution every T = 0.123 hours. What is the magnitude of the lift force acting on the plane? At what angle is the airplane banked?
